DRIVE SHAFT SUPPORT STRUCTURE FOR JET DRIVING VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a drive shaft support structure for a jet driving vessel with easy mounting work, narrowing an installment space and realizing low cost. SOLUTION: The drive shaft support structure 30 for the jet driving vessel 10 is provided in a duct 27 having an opening 27c through which a drive shaft 26 is penetrated. The drive shaft support structure 30 is constituted by a bearing part 31 provided on a peripheral surface of the drive shaft 26; an elastic part 32 provided on a peripheral surface of the bearing part 31; and a bearing part support part 33 for press-contacting the elastic part 32 with the bearing part 31. Further, the bearing part support part 33 is constituted by a base part 36 fixed to the duct 27; an elastic part support part 38 forwardly extending from the base part 36; and an elastic part fixing part 39 for fixing the elastic part 32 to the elastic part support part 38. Further, a cylindrical body 37 covering an outer peripheral surface of the drive shaft 26 is provided on the elastic part support part 38 and a space between the cylindrical body 37 and the bearing part 31 is sealingly closed.
